Safety first: No special safety concerns.

Improve signal: Move the Wi‑Fi router closer to the dock or use a 2.4 GHz extender near the robot’s home base.
Check router settings: Ensure 2.4 GHz is enabled, and that the SSID and password contain only standard characters.
Re‑add robot: Remove the robot from the Samsung app and perform the pairing process again.
If disconnections persist: The Wi‑Fi module may be degrading; continued cleaning is safe, but app features may require module or PCB replacement.

Robot vacuum does not connect to Wi‑Fi or frequently disconnects, but still cleans normally.
